Subject [jira] [Created] (CRUNCH-229) Better error handling for incompatible PTypes and Targets
Date Sat, 29 Jun 2013 00:01:20 GMT
Josh Wills created CRUNCH-229:
---------------------------------

             Summary: Better error handling for incompatible PTypes and Targets
                 Key: CRUNCH-229
                 URL: https://issues.apache.org/jira/browse/CRUNCH-229
             Project: Crunch
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.6.0, 0.5.0, 0.4.0, 0.3.0
            Reporter: Josh Wills
            Assignee: Josh Wills


Right now, this simple bit of Crunch code:

pipeline.read(From.textFile(...)).write(To.avroFile("output"));

...fails because the Writable type that is returned by From.textFile cannot be converted to
an Avro type for the output file. The current error message when this happens ("no OutputFormat
configured") is cryptic relative to the actual source of the problem. This patch moves the
error reporting higher in the stack to the source of the problem.
